Given δbae is isosceles with base angles ∠bea and ∠eba and that ∠aec = 115°, is δebc ~ δaec? if so, by what criterion? a) yes, by aa criterion b) yes, by sas criterion c) yes, by ssa criterion d) no, not possible to tell.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
